EBR74796472 LG Refrigerator Main Control Board Guide: Counter Depth, Standard Depth and Kenmore Cabinets on One Assembly, Where Cubic Feet Decide Nothing
Part EBR74796472 is the LG main control board catalogued as a PCB assembly, main. What earns it a guide is the shape of the fitment list attached to it. Published parts records put this one assembly behind a counter depth cabinet, a 25.4 cubic foot full depth cabinet, an ultra large capacity cabinet, LG export designations on the GC-B258 stem, and three Kenmore refrigerators sold under 795 numbers. Those appliances do not look alike, do not hold the same volume and do not carry the same badge. They take the same board. Every instinct a buyer brings to a parts lookup, that a bigger box needs a bigger part or a Kenmore needs a Kenmore part, is wrong here, which leaves the printed label as the only check with real authority.
What Does a Failing EBR74796472 Look Like From the Kitchen?
An EBR74796472 becomes a candidate when a bottom freezer cabinet warms through both sections at once, when frost sheets the freezer back wall because defrost stops finishing, when the compressor never starts on an outlet proven live, when the ice maker quits during a wider cooling complaint, and when the interior panel stops responding. None of those is proof on its own.
This assembly is where the refrigerator makes its decisions. Compartment sensors report to it, it decides when cooling is due, and its outputs run the compressor circuit, the fans, the defrost schedule and the ice hardware. Boards holding that many jobs announce trouble in a particular way. Rather than one component dying cleanly, several unrelated functions slip inside the same few weeks, because all they share is the part commanding them.
- Fresh food section and freezer both losing temperature over days, with the panel still lit and accepting settings
- Freezer back wall glazed in ice until almost no air reaches the upper compartment
- Ice production stopping at the same time as a temperature complaint rather than on its own
- A machine compartment that stays silent even though the wall outlet has been proven live
- Buttons on the interior control panel that no longer change anything

Why Does the Size of Your Refrigerator Prove Nothing on This Part?
Because the documented fitment for EBR74796472 crosses capacity classes, cabinet depths and brand badges all at once. One published list places it under a counter depth LFC21776, under a 25.4 cubic foot LFCS25426, under an ultra large capacity LFC25776, under GC-B258 export designations and under three Kenmore 795 numbers. Interior volume is not a sorting key here, and neither is the name on the door.
Shoppers sort refrigerator parts by size out of habit, and on most appliances that works. A larger cabinet usually carries a larger evaporator, a different door assembly, a differently rated compressor. Control electronics do not follow the rule, because a board is sized by how many circuits it drives rather than by how much air sits in front of it. LG built one logic platform for a run of bottom freezer cabinets, fitted it into boxes of several volumes and two depths, and later into Kenmore versions of the same machines.
The consequence is uncomfortable. Somebody with a counter depth refrigerator who reads that a part fits a 25.4 cubic foot model assumes the listing is wrong, and somebody with a Kenmore skips the LG listing entirely. Both assumptions cost money, and the reverse holds too: a board fitting a cabinet the size of yours proves nothing. Volume is noise. The eleven characters on your old board are the signal.
The video shows where the applied label sits on an appliance control board and how to read it before packaging is opened. On this part the habit does two jobs. It settles the capacity question, since no measurement of your cabinet tells you which board is inside it. It also settles a second question raised by the number itself, because EBR74796472 sits in a run of consecutive LG assemblies whose fitment lists have nothing to do with one another.
Which Complaints Point at the Board and Which Point at Something Cheaper?
Count the independent systems misbehaving. One failed function surrounded by healthy ones names the hardware performing it. Three or four unrelated functions drifting together names the assembly commanding them. On a cabinet of this generation that arithmetic settles most cases before a meter comes out.
Treat every row as a direction for testing rather than a verdict. These cabinets hand one board responsibility for two compartments, a defrost schedule, several motors and an ice module, which is why complaints starting in very different places converge on this part more often than the evidence supports.
| Symptom | What It May Indicate | Recommended Next Step | Board? |
|---|---|---|---|
| Both sections warming together, panel lit and responsive | Cooling is requested and not delivered, or was never requested | Watch each fan start, then read the compartment sensors at their connectors. A board fed impossible values behaves like a board that has stopped working. | Common |
| Freezer back wall packed with ice, airflow strangled | Defrost is not completing, or its heating path has opened | Meter the defrost heater, thermal fuse and defrost sensor first. The board only schedules defrost; three low cost parts must survive for the cycle to finish. | Defrost parts first |
| Compressor never starts, everything else appears alive | A start device, an overload protector, or the switching stage on the board | Listen at the machine compartment for repeated attempts against total silence, then examine the start components before condemning anything electronic. | Start components first |
| Cooling, defrost and ice all degrading in the same month | A shared point of command rather than coincidence | When systems sharing no mechanical parts fail together, what they do share moves to the front. Clear sensors and fans, then weigh the board seriously. | Board-related |
Do These Cabinets Even Show Error Codes, and What Do the Codes Name?
Some do and some barely do. The cabinets documented against EBR74796472 are bottom freezer models with modest control panels rather than large dispenser displays, so the readouts are fewer and plainer than owners expect from LG. Published code meanings also shift between LG series and revisions, so confirm any code against your own documentation before spending on it.
This is where a lot of research goes wrong. Search an LG refrigerator code and most of what returns describes the large dispenser cabinets, machines with a wide door display and a deep diagnostic repertoire. Several appliances on this fitment list are not built that way. Their controls are simpler, and a fault may show up as behaviour rather than as a code. A refrigerator misbehaving while displaying nothing is thereby proved neither healthy nor faulty.
Where a code does appear, sort it into one of two groups before acting. Most readouts name a component the board is only watching, so replacing that component closes the job cheaply. A smaller group describes a relay or a conversation inside the assembly. The table groups them by that logic rather than reproducing a code list, because a list copied from the wrong LG series is worse than none.
| Group | What It May Indicate | Is It This Board? |
|---|---|---|
| Readouts naming an evaporator fan | Rotation was not confirmed back to the board. Ice against a blade, a worn motor or an open supply raises this long before logic would | Fan first |
| Readouts naming a compartment sensor | A value that is shorted, open or impossible. The published LG sequence for this era begins at the connector and reaches the board last | Sensor first |
| Readouts naming defrost or its sensor | Defrost ran its window without reaching temperature. Heater, thermal fuse and defrost sensor all stand between instruction and result | Test the defrost circuit |
| Readouts describing a compressor relay | Either a switching stage the board owns, or a compressor that will not start for mechanical reasons. Separate the two before ordering | Separate the two |
| Readouts describing lost communication | Two assemblies that can no longer hear each other. The wiring between them fails more often than either end does | Harness before board |
| No readout at all while the cabinet stays warm | A refrigerator that has quietly stopped calling for cooling and does not regard that as a fault. This leans furthest toward the assembly | Board-related |
What Has to Be Cleared Before an EBR74796472 Is Worth Buying?
Four checks decide it: does the label on your removed board read EBR74796472 through to the final digit, do the compartment sensors measure sensibly, do the defrost heater and thermal fuse show continuity, and does the compressor attempt a start with both fans turning freely. Only the first is free.
This check belongs at the very start. The fitment list spans two cabinet depths, several capacities and two brands, so nothing you can observe about your refrigerator narrows it down. Worse, the number sits in a consecutive run whose neighbours serve different appliances, with AP and PS references one digit away. Read your label character by character and buy against that.
Nothing else feeds this board its picture of the refrigerator. Hand it a shorted, open or wildly implausible reading and its cooling decisions become nonsense, and at the kitchen door nonsense is indistinguishable from a dead board. The published LG sequence for this era arrives at the control assembly last for good reason. Sensors cost very little and fail regularly.
A freezer sealing itself shut with ice is among the commonest complaints on these cabinets, and cabinet logic is rarely responsible. The board schedules defrost; it does not produce heat. Completion needs current through a heater, a thermal fuse that has not operated, and a sensor still reporting a temperature. Remove any one and airflow chokes the same way each time.
A refrigerator that hums briefly and falls silent, or clicks without ever running, describes a start problem rather than a thinking problem. The start relay and overload protector at the compressor are inexpensive and fail regularly at this age. Condemning a control board for a fault living two feet away is a costly and ordinary mistake.
How Much Work Is an EBR74796472 Swap on a Bottom Freezer Cabinet?
Our product records place the EBR74796472 behind the rear access panel at the back of the refrigerator and put the swap under half an hour for a confident owner. The limiting factor is access rather than skill, since the cabinet must come away from the wall first.
The mechanics ask very little. A few screws, connectors released at their latches, an assembly lifted from its mounts. Time goes into moving a loaded refrigerator far enough forward to stand behind it, and into remembering which plug belonged to which header. Photograph the populated board before touching a connector.
Does the EBR74796472 Fit Your LG or Kenmore Refrigerator?
A model lookup is worth running here, because the documented fitment reaches across cabinet sizes and brands in a way nobody guesses. Enter your full model number, including any Kenmore 795 prefix, and check it against our records. Confirm against the label on your existing board regardless of the result, since consecutively numbered neighbours serve other appliances.
Model Number Check
Enter your model number to check it against our EBR74796472 compatibility records. Kenmore owners can type it with or without the 795 prefix. Not found? Use the buttons below to reach our team.
The applied white label is the only place all eleven characters appear together. Cabinet size will not tell you, the badge on the door will not tell you, and the model number alone can mislead where a previous repair has been done. Click to zoom in.
Which LG and Kenmore Models Are Documented Against the EBR74796472?
Independent parts records document the EBR74796472 against LG LFC21776 and LFCS25426 cabinets in more than one finish, against LG export designations on the GC-B258 stem, against three short form LG numbers, and against Kenmore 795.71602015, 795.71603015 and 795.71604015. One record adds LFC25776ST, which we mark separately as single source.
Documented Fitment, Confirm Against Your Label
Three points are worth drawing out. First, the capacity spread is documented rather than inferred: a counter depth cabinet, a 25.4 cubic foot full depth cabinet and an ultra large capacity cabinet all appear under one number, which is why the size of your refrigerator helps you not at all. Second, the Kenmore numbers are not an aggregation artefact. Three sources name the same three 795 codes, and the short form entries 71602, 71603 and 71609 line up with those machines under LG's own numbering. Third, several entries carry destination codes such as ASTCNA0, ASBCNA0, ASTCNA7 and ASWCSE5 after the model number. Those name the market a cabinet was built for and, on our evidence, do not change which board it takes. LFC25776ST is listed by one retailer only, so treat it as a lead to confirm.

How Is the EBR74796472 Restored to Spec? The FailSafe Precision Protocol
Every EBR74796472 sold by Appliance Pro USA goes through the FailSafe Precision Protocol, a proprietary 4-step process covering failure pattern analysis, precision diagnostic testing, proactive component replacement using equal or higher-rated parts, and final certification before the board ships.
FailSafe Precision Protocol
Failure Pattern Analysis
Known failure patterns for the EBR74796472 are mapped before any board enters the process, so we know exactly which components to focus on for this specific board type.
Precision Diagnostic Testing
Multi-point diagnostic testing identifies faults and confirms overall board condition. Boards that do not pass diagnostic testing do not advance.
Proactive Component Replacement
Components identified through failure pattern analysis as common weak points are replaced using equal or higher-rated parts, before the board is cleared to ship.
Final Certification
Certified to meet or exceed original LG factory specifications. Tamper-evident hologram applied. Anti-static packaged and sealed for shipping.
What Are the EBR74796472 Specifications and Cross-Reference Numbers?
LG catalogues the EBR74796472 as a PCB assembly, main, and four independent parts records describe it as a main control board rather than a display or inverter module. Its references are AP5977472, PS11710603 and EAP11710603, with retailer catalogue number 4119024 alongside vendor stock codes. No supersession is recorded against it in any source we checked.
| Manufacturer part number | EBR74796472. Catalogued through LG parts channels as PCB Assembly Main, and described in independent parts records as the refrigerator main power control board assembly |
| Board type | Main control board. Four separate parts records describe it in those terms, a stronger agreement than most numbers in this series attract. It is not a display assembly, not an ice maker board and not a compressor inverter module |
| What it controls | Compartment sensor inputs, cooling calls and compressor operation, evaporator and condenser fans, defrost scheduling, and ice hardware where fitted |
| Cabinets served | LG bottom freezer refrigerators across more than one capacity class and more than one cabinet depth, plus Kenmore badged equivalents under 795 numbers and LG export designations on the GC-B258 stem |
| Cross references | AP5977472 appears against this number in multiple records, with PS11710603 and EAP11710603 as its pair, retailer catalogue number 4119024, and vendor stock codes including ALG54572, PD00054757 and OEM17932425 |
| The consecutive block | EBR74796470 and EBR74796471 are separate assemblies for other cabinets, and their references run in arithmetic step with this one: 4119022 and 4119023 against 4119024, AP5977470 and AP5977471 against AP5977472, PS11710601 and PS11710602 against PS11710603. Cross references are therefore a weak second check here, not a strong one |
| Supply status | No supersession is recorded in either direction by any source we consulted. Availability disagrees sharply between retailers: one in stock, one special order, one out of stock and one backordered at the time of writing. Our own stock position is shown at the top of this page |
| Sibling caution | The EBR747964 group contains many distinct boards with their own model lists and references. Sharing the first nine characters proves nothing about fitment. Neighbours in the family cover LFX series French door cabinets and, in one case, a fitment split by production run |
| Board location | Behind the rear access panel at the back of the refrigerator, per our product records. Typical replacement time is under 30 minutes with a Phillips screwdriver and nut driver |
| APU status | FailSafe Certified, 1-year warranty (registration required), same-day shipping* |
Is an EBR74796472 the Right Spend, or Is It Time for a New Refrigerator?
Once sensors, fans, defrost hardware and compressor start components have been cleared and the board is genuinely at fault, replacing it is normally the least expensive route back to a working refrigerator, because the appliance around it costs many times more than the assembly inside it.
What your options typically cost
What Still Goes Wrong After the Correct Board Is Fitted?
Four things undo an EBR74796472 repair: ordering against cabinet size or brand instead of the printed label, leaving the sensor or defrost fault that caused the trouble, returning a connector to the wrong header, and judging the outcome before the refrigerator has pulled down.
Buying against the shape of the appliance rather than the label
This is the failure mode this number invites. Because one assembly covers cabinets of different volumes, different depths and two brand badges, people reason from what they can see and get it wrong in both directions. A refrigerator the same size as one on the list may take a different board entirely.
Skipping the sensors and blaming the replacement
A sensor stuck open or short feeds the new board the same impossible reading it fed the old one, and the refrigerator behaves exactly as it did before. Nothing on this list sends more good boards back to us.
Returning a connector to the header next door
Adjacent headers on this assembly are similar in size and keying, and a plug seated one position across produces behaviour nobody can tell from a dead board. The photograph taken before removal is the quickest way back.
Judging a warm refrigerator too early
A full size cabinet that has been open, emptied and warm does not reach temperature in twenty minutes. Calling the repair a failure too soon leads people to pull a good board back out. Close the doors, leave the settings alone and return several hours later.
Still not working after all of the above?
Contact our team before returning anything. A brief conversation resolves the majority of post-install situations. We stand behind every board we sell and are here to help you get the result you need.
Which Cheaper Parts Imitate an EBR74796472 Failure?
Parts capable of impersonating an EBR74796472 fault include the compartment sensors, the defrost heater with its thermal fuse and sensor, the evaporator and condenser fan motors, the ice maker module and fill valve, and the compressor start relay with its overload protector.

EBR74796472 LG Refrigerator Main Control Board, Frequently Asked Questions
These answers cover why one board serves refrigerators of different sizes, whether Kenmore owners are in the right place, what the GC-B258 designations mean, which references belong here and why they are a weak check, whether the part is discontinued, and what a single source listing is worth.
How can one board fit refrigerators of different capacities?
Because a board is sized by the circuits it drives, not by the volume of the cabinet around it. LG built one logic platform for a family of bottom freezer refrigerators and fitted it into boxes of several capacities and two depths. Records for EBR74796472 name a counter depth LFC21776, a 25.4 cubic foot class LFCS25426 and an ultra large capacity LFC25776 under one number. Ignore cabinet size and read the printed label.
My refrigerator is a Kenmore. Is an LG board really correct?
On these models, yes, and the evidence is unusually good. Three independent records name Kenmore 795.71602015, 795.71603015 and 795.71604015 against EBR74796472, with LG's short form numbers 71602, 71603 and 71609 alongside them in one catalogue. Kenmore refrigerators of this era came from several manufacturers, and these came from LG, which is why an LG assembly sits behind the rear panel. Type your number into the checker above, then confirm against the board label.
What are the GC-B258 model numbers on the fitment list?
They are LG export designations for cabinets sold outside the United States, appearing in the published fitment alongside the domestic codes. Records name GC-B258USNP, GC-B258USNZ and GC-B258VKNM, some extended with a destination code such as ASTCSE5, ASTCNA8 or ASBCNA0. Those suffixes name the market a cabinet was built for and, on our evidence, do not split the fitment. If yours carries one, send a photograph of it with the board label.
Which AP and PS numbers belong to this board?
AP5977472 is the reference recorded against EBR74796472, with PS11710603 and EAP11710603 as its pair, plus retailer catalogue number 4119024 and vendor codes ALG54572 and PD00054757. Read them carefully, because they are a weaker check here than usual. The neighbouring assemblies carry AP5977470 and AP5977471 with PS11710601 and PS11710602, and those serve different refrigerators. A reference misread by one digit lands you on the wrong board.
Is the EBR74796472 discontinued or superseded?
No source we consulted records a supersession in either direction, so the number stands under its own identity. Availability is where sources disagree. At the time of writing one retailer listed it in stock, another as a special order of roughly two weeks, another out of stock, and another backordered. That spread is normal at this age, and it is why our stock position is worth reading at the top of this page.
One site lists a model that another site does not. Which should I believe?
Neither, until your label agrees. LFC25776ST is the clearest example: one retailer lists it against EBR74796472 and the other records we checked do not name it. We have kept it in our list marked single source rather than quietly dropping or promoting it. Compatibility data for LG boards is widely copied between catalogues, so a model appearing once may be a genuine record or an error that has not spread. If yours is an LFC25776ST, photograph the board label before ordering.
My refrigerator is completely dead. Is that enough to condemn the board?
On its own, no. Total silence is equally consistent with a failed control assembly and with a compressor that cannot start, and the two are indistinguishable from the kitchen. Listen at the machine compartment: repeated attempts that fade, or nothing whatsoever. Prove the outlet, inspect the supply wiring, then look at the start relay and overload. Check your paperwork too, since the compressor and sealed system on LG refrigerators of this generation often carry longer coverage than the rest of the appliance. With that behind you, a refrigerator with power and no output makes a reasonable case for the board.
